I had this exact issue in 2008 in SF on Comcast Business.
The lease would be dropped and renegotiated every few hours, we could notice it because our SSH tunnels would get torn down.
What was annoying was that the business plan had a static IP associated with it, presumably managed by their DHCP setup.
It took weeks to convince Comcast the issue wasn’t in our building, and moments for them to fix once they “got it”.
- patneedham 6y agoWhat piece of evidence or logs finally convinced Comcast that the issue was on their side?
- dayjah 6y agoHonestly my memory is not that good! I remember a few tech visits as they replaced modems, etc, and I eventually got to some “3rd level support person” that said something akin to “oh, that issue again”.

Judges 12:5-6 (https://www.bible.com/bible/114/JDG.12.5-6.NKJV https://www.bible.com/bible/114/JDG.12.5-6.NKJV): > The Gileadites seized the fords of the Jordan before the Ephraimites arrived. And when any Ephraimite who escaped said, “Let me cross over,” the men of Gilead would say to him, “Are you an Ephraimite?” If he said, “No,” then they would say to him, “Then say, ‘Shibboleth’!” And he would say, “Sibboleth,” for he could not pronounce it right. Then they would take him and kill him at the fords of the Jordan. There fell at that time forty-two thousand Ephraimites.
- barbarbar 6y agoHaha - This is and the comment above are awesome. But not really a backdoor.
- landemva 6y agoI saw this daily drop on several small biz Comcast setups. I recall I found it while looking through all the settings on the router, though I do recall having to call Comcast and they set something so it never happened again. It was the Comcast device with built in wifi. Hardwired didn't glitch, just wifi.
- torwayburger 6y agoI could be wrong but this sounds more like NAT port issue given the frequency and static lease agreement on IP.
